2.7 光栅扫描显示系统和随机扫描显示系统的主要区别是什么？ 2.10 某彩色图形显示系统，CRT显示器的分辨率为800×600，能显示216种颜色，其帧缓冲器的容量应如何计算？ 2.11某彩色图形显示系统，CRT显示器的分辨率为1024×1024，它可以从217种颜色中选出215种来显示，其帧缓冲器的容量应如何计算？查色表的长度和宽度应为多少？ 2.12 假如某光栅扫描显示系统拟采用8英寸×12英寸的屏幕，其分辨率为每英寸100个像素。如果需显示2048种颜色，则缓冲器需要设计成多大容量？

图形学大作业的源码。关于代码的一些说明： 项目采用Qt编写，预先要安装Qt，建议4.7 4.8左右的版本，不建议5以上版本。 几个类的作用 MainWindow 整个游戏窗口 GLArea 游戏中央黑色背景的画面，是MainWindow的成员。各种openGL相关的操作在这里完成。 Raider3d 游戏主对象，是GLArea的成员。维护各种游戏数据，包括敌人的网格模型，背景星云等等。 CMesh VCG网格 解决方案视图中Helper文件夹下的各种类不需要太了解 主要的编写工作在Raider3d进行。实际上，全部任务就是要实现以下函数： 1.画准星 Raider3d::drawCross()　　　 2.移动准星 Raider3d::moveCross(CROSS_MOVE move) 3.画游戏背景星云 Raider3d::initStarfield() Raider3d::drawStarfield() Raider3d::moveStarfield() 4.判断玩家按下扳机后（空格键），当前的准星是否打中敌人 Raider3d::getHit() Raider3d::world2View(Point3f& w) 5.实现敌人被击中后的爆炸效果（敌人模型网格的边随机散开） Raider3d::computeEdgeList() Raider3d::startExplosion(int hit_id) Raider3d::drawExplosion() 阅读代码比较好的办法是从main函数开始进入，顺次看MainWindow、GLArea、Raider3d。

vs2008下 opengl实现，多边形扫描线填充算法。 用到glut库 鼠标左右键实现选点和填充
